How does the location of the thyroid glands allow for the proper regulation of thyroid hormones?
Homework Answers
Thyroid gland is a butterfly shaped gland which is located in front of trachea and just below larynx.Thyroid hormones are important for regulating body metabolism and development.Thyroid gland has a rich supply of blood by inferior and superior thyroid arteries, which arise from the external carotid and subclavian arteries.Compared to other tissues it receives a large supply of blood.It also has a rich lymphatic system which helps to supply and regulate the thyroid hormone.The gland is abundant with the supply of sympathetic and parasympathetic nerves. Some studies suggest that sympathetic stimulation or infusion of epinephrine or norepinephrine may increase secretion of thyroid hormone.

In secondary active transport, the sodium iodide transporter moves iodide into the thyroid gland from the blood plasma. It cotransports one I- for every two Na+ ions. In mammals, this protein is found predominantly in the thyroid gland, but also in salivary glands, kidneys, gastric mucose, ovaries, and, importantly, in mammary glands, where it is responsible for uptake of iodide into milk, delivering this important element needed to make thyroid hormones. The point of this process is the ACTIVE transport of iodide. Where...
